We've just been given a charity status for our lost and found pets in our local area. I'm a volunteer scanner have been for nearly 3 years. The lady who runs this group put me forward as one of the trustees which was an honour when we got the charity status, but I was not aware with being in an IVA this would disqualify me.

You need to look at the charities terms n conditions... bankruptcy is a definite no no but iva's are not always the case.
A quiet word with the chairman to explain what an iva is and how it differs from bankruptcy may help.
